To the guys who have upgraded TB and headers how much of a difference have you noticed? I know the g pushes around 140 stock, what numbers can I shoot for with v6 TB, headers, cat back, ram? While I'm at it does anyone really think a TB spacer is worth it? I've read alot of negative feedback on those. Thanks for your help.
